Why do coconuts have 3 holes in them?
As you may know, Coconut is a palm that evolved from palms with 3 fruits. Palmyra for example has 3 fruits in its husks. Now if you go back to the coconut, it has 3 eyes, it has 3 ribs, indicating conjunction. Once upon a time on the earth coconut also had 3 fruits inside the husk. Due to evolution all the 3 joined together and unified.
